5-5: Make the changeset note explicit about the Windows scope and the actual fix.Helps release notes consumers understand what changed and why.
-fix: Error: spawn npm ENOENT +fix(cli, windows): append .cmd to package manager commands to avoid "spawn ENOENT"packages/ui/src/cli/commands/install.ts (2)
37-40: Guard against empty command from resolveCommand for clearer failure.If resolveCommand returns undefined, you may try to spawn an empty string (or “.cmd” on Windows). Fail fast with a helpful message.
const { command = "", args } = resolveCommand(pm.agent, "add", [packageName]) ?? {}; console.log(`Installing ${packageName} using ${pm.name}...`); - await execCommand(withWindowsSupport(command), args); + if (!command) { + throw new Error(`Unable to resolve '${pm.name}' add command for ${packageName}`); + } + await execCommand(withWindowsSupport(command), args);Apply the same check in the update branch above.
3-3: Consider centralizing Windows command resolution inside execCommand.Moving the shim into ../utils/exec-command keeps all spawn behavior consistent and avoids future call-site drift.

46-48: Avoid potential “.cmd.cmd” duplication; keep the simple approach.Maintain the preferred simple strategy but guard against already-suffixed commands.
-function withWindowsSupport(command: string): string { - return process.platform === "win32" ? `${command}.cmd` : command; -} +function withWindowsSupport(command: string): string { + if (process.platform !== "win32") return command; + // Prevent duplicate suffix when resolveCommand already returns *.cmd + return command.toLowerCase().endsWith(".cmd") ? command : `${command}.cmd`; +}

File: packages/ui/src/cli/commands/install.ts:46-48
Timestamp: 2025-09-01T10:44:59.759Z
Learning: In the flowbite-react CLI install command, the maintainer prefers a simple Windows support implementation that appends .cmd to all commands on win32, rather than a more defensive approach, because they know the command will only be package managers from the resolveCommand function.

32-32: Good fix: Windows wrapper applied to the update-to-latest path.This addresses the ENOENT on win32 for the “update to latest” flow. LGTM.
40-40: Consistent application on the regular install path.Same Windows-safe invocation here—nice consistency. LGTM.
